First "sbuffetto" of our sun ..
NASA scientists keep under tight control the Sun: activity on its surface is recording the peaks out of the ordinary. Reported on the night between 3 and 4 August a solar tsunami.
real fireworks are those that are recorded these days by the satellites pointed toward the Sun Scientists NASA in the past few hours have seen an explosion out of the ordinary: the event occurred in correspondence of a sunspot as big as the planet Earth. A phenomenon that, according to NASA, it can be connected to even larger eruption.
These explosions are emissions of the solar corona that push waves of gas in the surrounding space: a solar tsunami, which scientists believe affects the Earth. The shock wave travels in space and goes up against the natural magnetic shield that surrounds our planet. The first visible effect of the tsunami is a true 'invasion' of northern lights. Have provided spectacular lights visible from the skies over northern Europe and North America from night of August 3. They are the brightest and most colorful in recent years.
But it is a phenomenon that goes beyond these spectacular emanations. Astrophysicists who are monitoring the sun explain that this is the first eruption of similar proportions to our planet and live out that an explosion like this that could destroy satellites in its path. The consequences would be serious: the communications would suffer significant damage. According to NASA estimates, raise the Telegraph, England could be without electricity and suffer long periods of blackouts. The communications would be almost impossible.
a devastating solar storm is expected in 2013. According to NASA, our computer networks and the power could be destroyed by the peak of solar activity expected in the coming years.
